STOP AND WASTE COCK.

E5PECIFICATION forming part 61' Letters Patent No. 306,020, dated September 30, 1884.

Application filed December .9, 1883.

obtain a stop-cock which will prove effective and useful; and to the accomplishment of the above the invention consists of the novel devices and combination of devices, as will be described and claimed.

Reference will be made to the accompanying drawings, in which Figurel is a longitudinal vertical section of the device; Fig. 2, a section 011 line 1 1 of Fig. 1, and Fig. 3 a view of a modified arrangement.

like letters refer to like parts in each view.

A denotes the globular casing, provided wih base a, for securing it by wood-screws, and screw-nozzles Z), c, and d, which form the water-passages, and an internally-screwthreaded neck, 0. Through neck 6 is inserted into the globular casing a spindle, B, provided on its inner end with two curved cranks, f

0 f, situated on diametrically-opposite sides of said spindle, and forming pivotal connection with two valve-rods, H L. A thimble, G, is passed over spindle B, and is screwed into the neck 0 of easing A, the inner end of said thimble being countersunk to form a bearing for a collar, h, of spindle B. Upon the outer end of thimble C is secured a cap-nut, D, in which is placed a spring, 2'. This spring encircles spindle B and has suitable bearings, and serves to keep collar h of spindle B firmly to its seat. The outer end of spindle B is adapted to receive and retain a crank, E, provided with weight E. To the nozzle b is con nected, by means of a coupling-nut, j, a wator-supply pipe, F. In the exterior face of said nozzle b is formed the seat for a rubber valve, G, which, through the medium of rod H, is pivotally connected with crank f of spindle B. To nozzle 0 of easing A is coupled a thimble, I, which forms the seat for a rubber valve, K, pivotally connected by rod L to crank f. By this arrangement it will be seen that valve G opens by being forced outwardly, while valve K is opened by being drawn inwardly, whereby when valve G is (No model.)

opened the valve K is forced to its seat by the action of the infiowing water, in addition to the other mechanism described, and when valve G is closed to shut off the water-supply it will be held firmly to its seat by the waterpressure. Each valve GK is cylindrical, with a conical end which fits the seat, and each is passed over the screw-threaded end of rod H or L, and is adjustably secured thereon by a nut, It. To the end of thimble I, hereinbefore referred to, is connected by a couplingnut,-l, a waste-pipe, J.

The operation is as follows: By raising the weighted lever or crank E the supply-valve is opened and the water admitted to casing A, and through opening d to parts to be supplied, the pressure. of said water serving to force and hold the exhaust-valve to its seat. By lower ing the crank E the position of the valves is changed and the water allowed to escape, the outer pressure serving to keep the supplyvalve to its seat.

It will be understood that the device de scribed is applicable as a stop-cock or as a supply and waste valve for water-closets, &c.

In Fig. 3 I have shown a modified arrangement of the parts. In this case the globular casing N is placed under ground, and has an inlet and outlet pipe, M M, and also a wastepipe, N. The valves 0 O are connected by suitable crank-arms, m, of a lever, 01, pivoted in the casing, and to the valve 0 is connected a rod, 0, which at its upper end is connected with the crank P, which is situated above ground, and to the outer end of which is secured a weight, P. The operation is the same.

Vhat I claim is 1. The combination, with casing A, of spindle B, provided with cranks ff, rods H L, and valves G K, secured to said rods, as and for the purpose set forth.

2. The combination, with casing A, of spindle B, provided with cranks ff, rods H L, valves G K, secured to said rods, and weighted crank E, as described and shown.

3. The spindle B, provided with crank f f and collar h, in combination with spring i, weighted crank E, rods H L, and valves GK, as described and shown.

In testimony whereof I aff x my signatur in presence of two witnesses.
